Waveform Design for MIMO Radars With Matrix Completion
IEEE Journal of Selected Topics in Signal Processing, 2015It was recently shown that MIMO radars with sparse sensing and matrix completion (MC) can significantly reduce the volume of data required by MIMO radars for accurate target detection and estimation. In MIMO-MC radars, the subsampled target returns are forwarded by the receive antennas to a fusion center, partially filling a matrix, referred to as the ...

Minimax Robust MIMO Radar Waveform Design
IEEE Journal of Selected Topics in Signal Processing, 2007We consider the problem of minimax robust waveform design for multiple-input multiple-output (MIMO) radar based on mutual information (MI) and minimum mean-square error (MMSE) estimation for target identification and classification. Recognizing that a single, precise characterization of target power spectral density (PSD) is rare in practice, we assume

Waveform design for TDM-MIMO radar systems
Signal Processing, 2020Abstract In this paper, we propose an efficient algorithm based on second order cone programming (SOCP) to design waveform for time-division-multiplexing (TDM) multiple-input-multiple-output(MIMO) radar systems. To this end, we optimize Peak Sidelobe Level (PSL) of the transmit sequence with constant modulus constraint.

Sixth International Conference on `HF Radio Systems and Techniques', 1994
HF over-the-horizon radars often use CW transmissions comprising repeated linear FM sweeps. The resolution and sidelobe performance in the range dimension are determined within each sweep, but Doppler information is extracted by processing together the outputs of a number of sweeps.

Constant envelope waveform design for MIMO radar
2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010A method for generating constant envelope (CE) waveforms to realise a given covariance matrix for a closely spaced MIMO radar system is proposed. In contrast to available algorithms, the technique provides closed form solutions for finding the required waveforms and suggests that waveforms can be chosen from finite alphabets such as binary-phase shift ...

MIMO Radar Waveform Design in the Presence of Clutter
IEEE Transactions on Aerospace and Electronic Systems, 2011Waveform design for target identification and classification in multiple-input multiple-output (MIMO) radar systems has been studied in several recent works. In previous works, optimal signals for an estimation algorithm are found assuming that only signal- independent noise exists. This work extends previous research by studying the case where clutter

Reduced PMEPR Multicarrier Radar Waveform Design
2019 53rd Asilomar Conference on Signals, Systems, and Computers, 2019Multicarrier radar waveforms have many desirable properties for many radar applications. The well known multifrequency complementary phase-coded (MCPC) radar waveforms based on the consecutive ordered cyclic shift (COCS) design can achieve a low peak-to-mean envelope power ratio (PMEPR).

Waveform Design and Optimization in Radar Sensor Network
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010We investigate the use of information theory to design waveforms for the measurement of extended radar targets in radar sensor networks (RSN). The different channel gains for transmitting signals from different radar sensors are introduced to model the radar system channel.

Classical radar waveform design
2012The waveform determines the delay-Doppler response of a radar system. From that response, one can derive the radar's range and velocity resolution and their ambiguities. This chapter explains the concept and motivation for pulse compression. It then describes narrow-band signals and their major signal processing and analysis tools - the matched filter ...
